Answer:

Option B is correct

Step-by-step explanation:

The graph represent the negative correlation.

In negative correlation there is inverse relationship between two variables. If value of one variable is increasing then the value of other variable is decreasing.

As seen from the graph when the value of x is increasing the value of variable y is decreasing

So, Option B negative correlation is correct.

Find all factors of 2x^3-3x^2-2x

Nesterboy [21]

ANSWER:

x, 2x + 1, x -2

STEP-BY-STEP EXPLANATION:

We have the following expression:

$2x^3-3x^2-2x$

We simplify as follows to determine the factors:

$\begin{gathered} \text{ We factor the common term:} \\ \\ x\left(2x^2-3x-2\right) \\ \\ \text{ Now we factor the following term} \\ \\ 2x^2-3x-2 \\ \\ -3x=x-4x \\ \\ 2x^2+x-4x-2 \\ \\ \left(2x^2+x\right)+\left(-4x-2\right) \\ \\ x\left(2x+1\right)-2\left(2x+1\right) \\ \\ \left(2x+1\right)\left(x-2\right) \\ \\ \text{ Therefore:} \\ \\ 2x^3-3x^2-2x=x\left(2x+1\right)\left(x-2\right) \end{gathered}$

The factors would be x, 2x + 1, x -2

How many ways can the words in d-r-a-g-o-n-f-l-y be arranged

GarryVolchara [31]

Answer:

362880 ways

Step-by-step explanation:

The word dragonfly has 9 different letters.

So, to find how many ways this word can be arranged, we just need to calculate the factorial of 9:

First letter has 9 possibilities

Second letter has 8 possibilities (one used)

Third letter has 7 possibilities (two used), and so on.

So the number of ways is:

9*8*7*6*5*4*3*2*1 = 362880 ways
